alt Hacker NewsI worry that optimistic updates is going to become trendy and applied to more software, but without any plan for the "sad path" - failed to sync, sync conflict, etc. Get ready for a whole new era of race conditions and frustration!

Don't you have the same problems with basic CRUD apps? Also you need to handle the sad path for every single request instead of having the sync engine do it all in one place.

well it has been the standard for non critical feedback.
I would not implement optimistic resolution in key information, prices, for example. They live in the server and backend should keep the total control in the client side, even feedback response time.

based on my experience, this is a great description of the sync implementation in many already widely deployed products (say, off the top of my head, OneNote, OneDrive)
